Alberta Environment offers river flows and levels across several watersheds in the South Saskatchewan River Sub-Basin.

The Water Survey of Canada offers near real time river levels, and historical river discharge levels for some of the watersheds in the SEAWA region, including the South Saskatchewan River at Medicine Hat.

for historical daily river discharge flows

On average, the South Saskatchewan River, measured at Medicine Hat, has its highest flow rate in June. The average peak flow rate is about 700 cubic meters per second. This drops down to a minimum of about 80 cubic meters per second in September or October.
Let’s compare with other River Basins

On average, the Bow River measured at the mouth of the river ranges from about 200 cubic meters per second in June to about 30 cubic meters per second in early to mid-October.

The Oldman River measured near Lethbridge ranges from more than 300 cubic meters per second in June to about 20 m3/s in August. The Oldman River measured near the mouth of the river ranges from about 200 cubic meters per second in late May to about 30 cubic meters per second in August.

The Red Deer River measured at Red Deer ranges from more than 100 cubic meters per second in June to less than 20 cubic meters per second in April. The same river measured near Bindloss, farther downstream, ranges from more than 100 cubic meters per second in June to less than 30 cubic meters per second in October.
